What elements have less than eight valence electrons?
Any element except the elements in group 8, 9, 10, 11, 12 and 18 have lesser than 8 valence electrons.
Are valence electrons the number of protons?
Only for hydrogen and helium are these two numbers the same. All other elements have at least two non-valence electrons, and the total number of electrons must be equal to the number of protons. Therefore, in all elements except hydrogen and helium, the number of valence electrons is less than the number of protons.
How do you count the valence electrons of an atom?
Take the atomic number then subtract the amount of valence electrons. Example: Number of non valence (inner) electrons in Sulfur: 16 (atomic number) - 6 (valence electrons) = 10 (valence or inner electrons)
Why are valence electrons easier to remove from an atom than core electrons?
the force of attraction between then nucleus and the valence electrons is less than that between the nucleus and the core electrons
What element is most reactive an en element with 7 valence electrons or an element with 8 valence electrons?
the element with seven valence electrons will be more reactive. The reason for this is that elements want to always want to have a full valence shell (they always want 8, like a noble gas). The element with eight valence electron is happy with its full shell and will not want to get rid of any electrons.

Which elements is less reactive an element whose atoms have seven valence electrons or an element whose atoms have eight valence electrons?
the element with seven valence electrons will be more reactive. The reason for this is that elements want to always want to have a full valence shell (they always want 8, like a noble gas). The element with eight valence electron is happy with its full shell and will not want to get rid of any electrons.
What happens to the reactivity of metals from left to right across the perriodic table?
Elements become less reactive as you move from left to right across the periodic table. This is due to how many valence electrons (outer-most electrons) the element has; the less valence electrons, the more reactive the element.
What element has an atomic number lower that that of aluminum and one less valence electrons than the group 16 elements?
Nitrogen
What is the difference between a valence electron and a shielding electron?
Valence electrons are electrons on the outermost shell/orbitals. Sheilding electrons are inner electrons that block valence electrons from protons causing less attraction.
What is the relationship between the number of valence electrons and the conductivity of the given elements?
Less valence electrons (1 to 3) in the outermost shell of an atom usually means a good conductor. (silver, cooper, gold). 5 t0 8 valence electrons are found in glass, rubber, ceramic, plastic, non-conductors.
How do you count the valence electrons of an atom?
Take the atomic number then subtract the amount of valence electrons. Example: Number of non valence (inner) electrons in Sulfur: 16 (atomic number) - 6 (valence electrons) = 10 (valence or inner electrons)
Two elements are found in the same column of the periodic table You would expect these elements to have?
same number of valence electrons, so are their chemical properties more or less the same.
What do bromine and chlorine have in common?
The atoms of both elements have seven valence electrons and a strong tendency to abstract, from a less electronegative atom, an electron to complete their valence shells and thereby become an anion.
The number of electrons in the outer energy level of Group 17 elements is?
there are 7 electrons in the outer energy level of group 17 elements
When an atom or an ion has 8 valence electrons it is more or less stable than when it ha fewer than eight valence electrons?
Valence electrons are the amount of electrons in the outermost electron shell. 8 valence electrons fill the outer shell making it completely stable.
